John, reading the Kiwanis mission, they exist to support children's ability to prosper. Given that, I would say that support for comfortable, safe, consistent and efficient pedestrian and bicycling infrastructure is essential for youth mobility. If you have an opportunity to seek funding from them, you could start with auditing those facilities and start planning for any needed strategic improvements.
Independent youth mobility is critical to ensuring they have the ability to stay moving and healthy.
I've started working with our local school district to introduce bicycle education into the physical education programs for elementary and middle schools. This could be a gym class for a week learning how to properly ride on streets.
Good luck. Next reach out to your local Rotary Club as they have civic/community strengthening values.
